Maltby KE4 ST-A1 Driver

The KE4 ST-A1 adjustable driver is a game changer! Game changing in that it gives professional club fitters and avid golfers the ability to customize driver head specifications to optimize ball flight. Using a proven adjustable hosel design that allows 26 distinct settings, the ST-A1 designed square face angle can be adjusted from 3 degrees closed to 3 degrees open by changing the FCT adjustable hosel sleeve settings using the FCT torque wrench. Multiple options in between the maximum closed (C) and open (O) location allow for face angle adjustments at lesser amounts, providing true fine tuning of directional flight and trajectory. In additions, the lie angle can be adjusted independent of the face angle. The "N" or neutral setting provides a standard lie angle and the "NU" neutral upright setting on the FCT adaptor provides a 1.5 degree upright lie angle. Two designed loft options provide vertical flight control, with the 9.5 degree loft option providing low-to-mid trajectories and the 10.5 degree loft option providing mid-to-high trajectories. Players of all skill levels, with the right amount of adjustment, can find the perfect setting to optimize their ball flight.

FCT Standard Hosel Settings

"N" Setting - The "'N" setting is used for a neutral face angle, lie angle and designed loft angle. This setting promotes a straight ball flight and a trajectory true to the designed loft angle

"O" Setting - The "O" setting can be used to the club face. This setting promotes a left-to-right ball flight helping to reduce hooks with a trajectory true to the driver heads designed loft angle.

"C" Setting - The "C" setting can be used to close the club face. - This setting promotes a right-to-left ball flight helping to reduce slices with a trajectory true to the drivers designed loft angle.

"NU" Setting - The "NU" setting is used for a neutral or square face angle with an upright lie angle. This setting promotes a draw and a trajectory true to the drivers designed loft.

great head for your $$$Had this driver built for me by my dad. It was fit with an Aldila Serrano Stiff shaft that was trimmed for a bit more stiffness. This driver is a monster. I still need to tweak it a bit to find a sweet spot, but set on Neutral I feel comfortable addressing the ball and launching it well over 300yrds. The loud PING sound it makes is nice too. Total assembled cost was about $225. You can't find a driver of this quality for anywhere near that cost.

Great DriverAbsolutely a great driver! It is absolutely a beast and has a great sound to it. Very forgiving and adjustable hosel and weight port adjustability is great for dialing in ball flight and the swingweight I want for my 44.5" driver. Only complaint I have is the head I was sent had a small ding in the paint on the crown I had to fillin with a sharpie.

Quality driverI thought I need this head for its adjustable features, but after assembly at zero adjustment for face angle, I am hitting longer and straighter than ever. Great investment.

how do i make adjustments to the head and how do i know when the right adjustment is made for example a closed face adjustment and what does it look like on the hosel in relation to the head an o setting or c setting or n setting i guess i need instructio

Asked by: golf man

To make an adjustment, loosen the adaptor and position the setting you want (C, N, NU, or O) and the corresponding line on the adaptor centered on the backside of the hosel. The C is for a close face, the N is for a Neutral or square face, the NU is for a Neutral / Upright face and lie angle and the O is for an open face angle. Once you have positioned the adaptor in your preferred position, tighten the adaptor in place.

I closed the trunk on my shaft. The shaft broke about a foot from the clubhead. I am concerned about the adjustable [ferrule] being damaged when I remove the shaft. ?Do you have a recommendation on how to remove it? ?A tutorial or web link would help

Asked by: nonverbal

The adjustable adaptor or ferrule on this driver is totally aluminum. There is no plastic ferrule to damage. Using our OEM Adaptor Saver Kit and a graphite shaft puller is the easiest way to remove the adaptor.

Thread the proper size screw through the washer and install into a graphite shaft puller as shown in the picture. Heat the adaptor and use the shaft puller to pull the adaptor off the shaft tip.

What adjustable head weights come with the club. ?Does the wrench that comes with the club also work with the head weights?

Asked by: Dave 210

A 6 gram weight comes with each head. Additional weights can be purchased here: http://www.golfworks.com/product.asp_Q_pn_E_MA002GT
The wrench that comes with the driver will work on both the FCT hosel adaptor and the triangle screw weights.

Does the FCT Adaptor Sleeve, come with the Maltby KE4 ST-A1 Driver or is it an additional charge? Thank you

Does this head require a threaded shaft?

Asked by: Artie

The ST-A1 driver is an adjustable driver that has a hosel piece that is epoxied to the shaft. This piece is then inserted into the head at the specification that works for you, and is attached by the screw in the sole. It does not require a threaded shaft.

Do I need the FTC adaptor sleeve

Asked by: Cagykay

The driver comes with adjustable sleeve. You wold only need an additional sleeve if you wanted to have a second shaft option available that you could change out.
